Title: Plastic bonded explosive briquettes - obtd. using microencapsulated catalysts ruptured only during pressing for long mixing times
IPC: C06B45/10
Filed: 1974-05-27
Abstract: Explosives e. g. nitrocellulose, nitroglycerine, pentaerythritol tetranitrate, are bonded with a thermosetting or chemosetting plastic mix which contains the catalysts required for initiating and accelerating the polymsn reaction in a microencapsulated form. The encapsulated catalysts are protected from the plastic binder during mixing with the explosives and therefore long mixing times and intimate mixings can be obtd. without premature setting of the binder. When fully mixed the prod. is pressed into compacted shapes, during which pressing operation the microcapsules are ruptured, the catalyst is freed to mingle with the binder and polymsn. to a solid bonded charge follows automatically without further processing. Process is esp. for propellent mfr.

Title: Steam production process - obtains low pressure steam via heat exchange with vaporisable fluid in closed circuit
Inventor: ROGEY ALEXANDRE
IPC: F22B3/02
Filed: 1974-12-03
Abstract: The process produces steam at two or more different pressures, part of the medium pressure steam being obtained by partial expansion in a turbine of high-pressure steam. Part of the low-pressure steam is obtained by vaporising water in a first heat exchanger with indirect contact with a vaporisable heat exchange fluid circulating in a closed cycle. This fluid is condensed in a first heat exchanger, expanded, and vapourised in a second heat exchanger by indirect contact with a heat source at a thermal level lower than that of saturated steam at the low pressure concerned. It is then compressed in a compressor which is mechanically driven by the turbine and returned to the first heat exchanger.

Abstract: Clothing articles are loaded and taken out from the top. The lid slides on the sleeve of the drum so as to ensures its opening and closure. One of the side-edges of the lid is bent in the form of a collar and rests on the rim as a flange, which forms the seating for the ring of the drum with one of its end-walls, while the other side-edge of the lid is bent at right angles, to the edge similarly forming a collar and resting on the rim of the other ring, which the collar completely covers. After the mounting of the lid, a small right-angled elbow is permanently fixed, with a series of rivets, to the internal surface of the right-angled collar, this elbow following the curved path of the lid, its free wing acting under the projecting part of the corresponding rim, thus ensuring the position of the lid on the drum. There is no need to mount a catch on the drum and deep stamping operations are dispensed with.

Title: Self regulating hydraulic pressure valve for tipper vehicles - has restricted flow when lifting and unrestricted flow when lowering
Inventor: KATAINEN KALERVO
IPC: F16K31/363
Filed: 1975-09-05
Abstract: The valve consists of a housing containing a spindle whose upwards movement is resisted by an adjustable set of springs. The space above the spindle is open to atmospheric pressure. The hydraulic pressure medium enters the valve housing at the inlet union situated close to the end of the regulator spindle and fills a chamber formed in its base to flow through a suitable restrictor bore against the spring pressure and atmospheric pressure to the outlet union whereby the restriction decreases progressively to the pressure increase. The outlet pressure chamber is separated from the spring chamber by a sealing ring.

Patent FR-2337919-A1 (FR)
Title: Spacing grid for nuclear reactor combustible assembly - has spring holders, and slots in grid increasing holder flexibility
Inventor: FEUTREL CLAUDE
IPC: G21C3/34
Filed: 1976-01-09
Abstract: The grids are formed by perpendicular plates fitted together to form cells of square section. The plates have large hollowings sepd. by corrugated bands. The bands project into the cells and act as springs, holding rods of the combustible assembly against other such springs and against bosses in the flat parts of the sheets. Each rod is thus held in two different directions at four points regularly spaced around its periphery and at several points in its length. The cooling fluid circulates around the assembly through the openings, and the bands and bosses absorb vibrations. The invention improves the grid by increasing the flexibility of the springs so that they exert sufficient, but not too much, force in supporting the rods against the bosses and provide for variations in the dia. of the rods and the dimensions of the cells. This is achieved by creating a zone of reduced mechanical resistance in the plates, by making slots in the sheets where they join the bands, so that the plates can be distorted between the slots and the bands. This distortion is added to the bending of the bands. The curve of force exerted by the spring as a function of its bending is as flat as possible. Better equilibration of the support pressures, a greater range of operation, more uniform distribution of mass across the structure, less vibration and less wear of the rods are obtd.
Patent FR-2343706-A1 (FR)
Title: Photochromic glass mfr. with varying photochromism - by varying heat treatment to give varying silver halide crystallisation
Inventor: ASTRUC CHRISTIAN GUY
IPC: C03B32/00
Filed: 1976-03-08
Abstract: Photochromic glass is made by heat treatment of a special glass compsn. to develop silver halide crystals etc. The glass is radiation treated by different amounts in different parts so that it exhibits a range of photochromic colours, i.e. a modulated photochromic anisotropy. The glass is used in sunglasses car windscreens etc. In prior art flat pieces of glass from a furnace had to be heat treated at a low temp. (500-600 degrees C) for bending so as not to disturb the photochromic effect. This requirement is now removed.

Title: Sepg. solids from liq. suspension esp. biological sludge - by electrophoretic deposition of particles on immersed electrode
IPC: C02F11/15
Filed: 1976-10-13
Abstract: The suspension is subjected to an electric field between two electrodes of opposite polarity. Particles migrate by electrophoresis to become deposited on one electrode from which tye are scraped and collected as a practically dry sludge. The electrode on which particles are deposited is pref. alternately immersed in the suspension for deposition and then brought out for scraping. An electrode in the form of a rotating disc conveniently provides the alternating cycle. The process can be effected with a batch of suspension which is processed until satisfactorily sepd. Alternatively the process plant can receive a continuous supply of incoming suspension, sepd. liq. being recycled into incoming suspension until purified. Used for sepg. solid particles from liq. suspension, partic. colloidal particles in biological sludge arising from the purificn. of industrial and/or domestic waste water. Used also as an industrial separator to replace filter presses in the paper-making and rubber industries. System provides a sludge dried to only a few per cent moisture content, and does not rely on filters which rapidly block and lose efficiency.
